Farewell world, hello . . . Alpha Centauri????

Actual conversation, words spelled properly, rather than as pronounced by Z-monster:

Z (holding lego rocketship): eight-nine! (Z lingo for "countdown")
S: Ooooh, Z, what a nice airplane!
Z: No, Daddy, no airplane. Rocket!
S: Oh, ok. What a nice rocket!
Z: Me fly bye-bye! Up, up, up!
S: Wow. Are you going to the moon?
Z: No
Me: Mars?
Z: No
S: Venus?
Z: No
S: Jupiter?
Z: No
S: Saturn?
Z: No
S: Pluto?
Z: No (giggles)
S: Alpha Centauri?
Z (pauses thoughtfully): Uh-huh!
S: You're going to Alpha Centauri???
Z (getting excited): Uh-huh!!!
S: Who is coming with you?
Z: Mommy, Ay-Ay, Didi, kitty, Buzz, and Daddy!
(at this point, countdown commences)
Eight! Nine! Four! Three! Five! One! Go!
(the rocket lifts off, accompanied by much rumbling)
Bye Mommy! Bye Daddy! Bye Ay-Ay! Bye Did! Bye home! Bye house!
